MOTOR GOVERNOR.

Application filed January 31, 1927; Serial No. 165,014.

My invention relates to improvements in motor governors, and the objectof my improvementis to supply auxiliary means for automaticallygoverning the fuel supply delivered to the inlet manifold of an internalcombustion engine, so that'the speed'of the engine may be properlyregulated, especially when it is used for the operation of machinery,and particularly when the engine 1s that of a motor car.

This object I have accomplished bythe means which are hereinafterdescribed and claimed, and which are illustrated in the accompanyingdrawings, in which Fig. 1 1S a side elevation of' a water circulationpump of amotor'car, whose rotary shaft is provided with a governor, andthe latter being operatively related to connecting-means adapted toactuate an auxiliary carbureter valve. Fig. 2 is a top plan of thedevices of said Fig. 1, including a horizontal fragmental section of acarburetor showmgsaid auxiliary valve mounted in its delivery passagefor the fuel to be supplied to an engine.

is a diminished plan diagram, showing an internal combustion engineequipped with my motor governor and connections.

My invention is not restricted to the precise construction andarrangement of parts herein shown and described, nor to the variousdetails thereof, as the same may be modified or rearranged in variousparticulars without departing from the spirit and scope of my invention,one practical embodiment of which has been herein illustrated anddescribed without attempting to show all of the various forms andmodifications in which my invention might be embodied.

My invention pertains particularly to the speed regulation of the motorof a Ford motor car, although it may be adapted for employment on othertypes of cars. It is suitable to be furnished to farmers and others foruse in driving various kinds of machinery, such as mills, rotary saws,feed cutters, by using suitable driving attachments connected to anddriven directly by the motor of a car. In these uses, it is desirablethat the speed of the motor be automatically regulated to apredetermined limit.

The numeral 29 denotes the motor of a Ford car diagrammatically, havinga carbureter 27 in communication with its inlet manifold 37, and havingon its crank-shaft a pulley (neither being shown) connected by a belt 34to apulley 35 on the rotary fan-shaft tatab'ly upon the shaft.

35 inthe'usual way, the belt 34 being carried around a pulley 4 securedupon the forward end of a rotary pump shaft 3 positioned alongside theleft-hand side of the motor.

The motor has the usual watenjacket communicatingat the top withaconduit 33 and the top of a'radiator 30, and the bottom of the radiatoris connected by a hose 32 with a delivery spout 31 on the under sideofthe casing 2 of a rotary pump, said casing being in communication withthe waterjacket and being integral with a frame memher 1 having at itsforward end a tubular bearing part 5 seating the forward part of thepump-shaft 3 directly back of the said pul'ley 4.

A collar 6. is secured upon said shaft 3 back of the bearing sleeve 5and spaced longitudinally from an annularly grooved. sleeve 7 which ismounted slidablynon-ro At opposite sides the collar 6 and grooved sleeve7 are connected by means of light, narrow elastic bars 9 which carry ontheir outer faces medially and secured thereto the hemispherical weights10.

The frame member 1 is spaced sufiiciently from the weights 10 as to becleared by them when rotating at their farthest outward limit ofmovement. The frame member 1 has a vertically apertured lug l2projecting part way toward the annular groove 8 of the sleeve 7, itsaperture seating a short vertical rock-shaft 13 having its upper partbent at a right angle and terminating in a flattened lozenge-shapedcontact head 11' seated in said annular groove 8 in a position to engageeither annular rim thereof when the sleeve 7 is moved longitudinally ofthe shaft 3 by the operation of the centrifugally acting weights 10 whenthe shaft 3 is in rotation. The lower end of the rockshaft 13 is bentinto a crank 14 whose termination is seated loosely in the rear eye 15 rupturned end cranks 1S and 21, the crank v 18 being loosely received inthe forward end eye 17 of the connecting-rod 16. The other crank 21 isloosely received in the forward end eye 22 of another connecting-rod 23positioned alongside the opposite side of the motor 29. I

A portion 'of the' carburetei' .delivery'necl; 27 is shown in Fig. 2. Inthis neck is shown in plan the usual throttle-valve 28 ofthe butterflytype adapted as usual to benianually set at a desired angle in more orless restricting the fuel passage of said'nec'k; I

have inserted a junction-body 36 between said carburetor neck 27 and theinlet-manifold 37, and have provided a rock-valve 26 in saidjunction-body .l'iaving an upwardly projecting stem 25 upon whose outerand upper end is secured a crank 24 with pin seated loosely in a rearend eye of the side connecting-rod I I do not claim the rotary pumpQadapted to force water circulation from and to the water jacket .of themotor through said radiator80; but it ismy intention to utilize thepuinpshaft 3 to carry the governor shown to-thus control by convenient meansthe auxiliary carburcter. valve 26 to thus varying fuel supply of themotor in the automatic regulation of the speed thereof predetermined, inalimit fixed by the previous setting or adjustment of the throttlevalve28. The motor may then be employed in operating machinery through themedium of, appropriate driving connections to the crank-shaft of themotor.

The operation of the governor will be apparent in its action upon theabove described connections to the valve 26, to variably restrict thedelivery of fuel through the hollow body 36 to the inlet manifold 37.

Having described my invention, what I claim as new, and desire to secureby LettersPatent, is:

The combination with a motor having :an inlet manifold, a carbureter incommunica tion therewith, and a rotary pump shaft driven by saidinotor,said carbureterhaving a throttle-valve. for fuel delivered to theinanifoldland. also having a rock-valve succeeding the throttle-valve infurther controlling the delivery offuel to'the' manifold,

a centrifugal governor mounted on said shaft, a rock-shaft having acrank moved to and fro by a moving element'fof'ithe gev crnoit andlinking connections between said rock-shaft and the secondment'ioned'roclzvalve whereby the'govei'n'or acts to control the rockingof said valve automatically up to a limit of delivery of fuel therebypredet-ermined by thejadjustment of position of said throttle-valve.
